Avoid using HTML in translation strings (wp-includes/customize/class-wp-customize-custom-css-setting.php)
|Reported by:||SergeyBiryukov||Owned by:||SergeyBiryukov|
In the past, we've made an effort to remove <code> tags from translatable strings, as they generally do not need to be translated.
 introduced a bunch of new strings with <code> tags in WP_Customize_Custom_CSS_Setting class for displaying error messages when validating custom CSS rules.
I've just stumbled upon a string where <code>content: "";</code> was translated literally, which means we should remove non-translatable parts from these strings.
